THOMAS H. OUTERBRIDGE, OF HAMILTON, BERMUDA.

HUB-LOCK.

SPECIFICATION forming part of Letters Patent No. 234,801, dated November23, 1880. Application filed September 3, 1880. (No model.)

To all whom at may concern Be it known that I, THOMAS H. OUTER- BRIDGE,of Hamilton, Bermuda, have invented anew and useful Improvement in Hub-Locks, of which the following is a specification.

My improvements relate to devices for securing wheels to axles, and havefor their objcct to dispense with the screws and nuts generally used forthat purpose, and to furnish a lock that shall secure the hub safely tothe spindle and can be readily manipulated.

My invention consists in a locking-tumbler combined with a case that isfitted for rotation on a spindle having a collar for retaining the case,for use in connection with a hub having lugs with which the tumblerengages to retain the hub in the spindle; also, in a spring combinedwith the tumbler to render the locking action automatic, and in certainother details of construction, that are set forth hereinafter.

In the accompanying drawings, forming part of this specification, Figure1 is a face view of the look as applied to a hub. Fig. 2 is alongitudinal section of the hub and lock on line a; m of Fig. 1. Fig. 3is an end View of the hub with the lock removed. Fig. 4 is a face viewof the lock-case with the cap and tumbler removed. Fig. 5 is anelevation of the tumbler, and Fig. (5 an elevation of the cap-plate.

Similar letters of reference indicate correspondin g parts.

A is the hub, fitted with a box for receiving the spindle, and B is thespindle, provided with a collar, a, that sits within a recess formed forit in the end of hub A. At the inner end of the hub there are lugs b,preferably three in number, which lugs may be formed with and projectfrom a cap-plate secured on the hub, or they may be the ends of T-boltsthat pass into or through the hub, so as to be held securely. Theseprojecting lugs Z) are formed with apertures in a line concentrio withthe hub.

O is the lockcase, fitted with tumbler D, and with the cap-plate a,covering the tumbler. The case 0 is a cup-shaped casting, formed withstuds (7, to which plate 0 is secured by screws, and with apertures cfor the are apertured to set over spindle B, so as to i turn freelythereon. The tumbler D is capable of a partial rotation independentlyfor looking and unlocking, and, if desired, the case 0 i is fitted witha central hub or sleeve, around which the tumbler is placed so as toturn thereon.

In Fig. 5 the tumbler D is shown as fitted with a spiral s1')ring, h,which, when the tumbler is insertedincascO, is compressed against astud, i, in the case, so that the spring tends to turn the tumbler inthe direction for looking. In place of aspiral spring a piece ofspring-wire may be coiled in case 0, as shown by dotted lines in Fig. 4,one end being caught on stud d and the other end engaged with a pin, 70,on the tumbler.

The cap 0 is slotted, as shown at lin Fig. 6, for insertion of a key tomove the tumbler back in unlocking or a pin from the tumbler may projectthrough the slot. There may also be a spring-catch attached to the innerside of case 0, for engagement with a pin on the tumbler when the hub islocked, and arranged for disconnection by a key inserted through theslot in cap 0.

It will be seen that when the hub is placed on the spindle the lugs I)pass through the case 0 and tumbler D, and are caught by the boltsf ofthe latter, so that the hub is held securely.

To remove the hub the tumbler will be turned back, thereby disengagingpins f. The

cap 0 retains the tumblerin the case, and also serves to exclude dust.

The hub may be provided with the usual dust-band to extend over thelock-case.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. In hub-locks, the tumbler D, provided withpins f and spring h, combined with the apertured case 0, having stud i,spindle B, which pass the lugs b of hub, as and for the having collar a,and hub having apertured purpose specified. lugs 12, substantiallyiasand for the purposes set forth THOS.
